“How many college freshmen does it take to screw in a lightbulb?” (joke)

Students at one college or university often tell a joke about a rival school:
 
Q: How many (insert college name) freshmen does it take to screw in a lightbulb?
A: None. That’s a sophomore-level course.
 
The joke has been cited in print since at least 1997, when it was told about the University of Michigan.
